Philadelphia police say 18-year-old Robert Sneed stepped outside a corner grocery store around 4 p.m. Monday and was shot multiple times in the torso. He was pronounced dead at a nearby hospital.

The shooting was the result of an argument, police said.

Cops tell the Philadelphia Daily News that a witness saw the shooter run into a nearby house with two other men. That witness alerted police to the address, and cops took all three men into custody and found a handgun hidden in a closet inside the row house, Chief Inspector Scott Small told the paper.

The investigation is ongoing and so far no charges have been filed.

Nearby crew members who were setting up when the gunfire erupted described the scene as “crazy” and “surreal.”
